At what velocity (m/s) must a 20.0g object be moving in order to possess a kinetic energy of 1.00J ​

10 ms-1

Explanation:

Kinetic energy = 1/2 × m × v^2

1 = 1/2× 20 ×10^ -3 × v^2

v ^ 2 = 100

v = 10 ms-1

note : convert grams in to kg before substitution as above

maybe the spark is gone, love is a weird emotion and there is a possibility he may have found somebody else.

u i forgot the answer?
